Melatonin is a hormone produced by the pineal gland in the brain that plays a crucial role in regulating sleep-wake cycles. Often referred to as the «sleep hormone,» melatonin is released in response to darkness, signaling to the body that it is time to wind down and prepare for sleep. Its production is inhibited by light, which is why exposure to screens before bedtime can interfere with sleep quality.
